Windows 10 1709 Version 16299.251

I just dnloaded the latest update to Windows 10 1709 version 16299.251 This update fixed an issue with some antivirus software issue. Below is a topic / comment they made. Is my Norton program compatible and does it have this fix?

Contact your antivirus manufacturer to verify that their software is compatible and that they have set the following REGKEY on the computer:

Re: Windows 10 1709 Version 16299.251

This registry key [Key="HKEY_LOCAL_MACHINE" Subkey="SOFTWARE\Microsoft\Windows\CurrentVersion\QualityCompat" Value="cadca5fe-87d3-4b96-b7fb-a231484277cc" Type="REG_DWORD” Data="0x00000000”] was originally added by Norton around the time that v22.11.2 was released in Nov 2017. I currently have Norton v22.12.1.104 and can confirm I still have that registry key.

However, users in PhoneMan's 06-Mar-2018 threadWindows Update KB4090913 & NSBU are now reporting that a recent Norton v22.12.1.x update (either the buggy v22.12.1.14 update that was pulled on 02-Mar-2018 or the v22.12.1.15 that is now being rolled out) might have incorrectly removed that key.

I haven't received the v22.12.1.x update yet so I can't confirm this bug myself, so I would advise monitoring PhoneMan's thread for further feedback. In the meantime, you can use the Windows Registry Editor (type regedit in the Run dialog box - see the Lifewire article <here>) to browse through your registry to see if the required key is still present on your own machine.

At the bottom of this article it shows 32-bit Vista Home Premium SP2 ......

What you are seeing there is the forum signature line, where lmacri is just letting us know what operating system and software versions they are using. That line appears on every post that lmacri makes in the forums.

The KB4090913 (OS Build 16299.251; released 05-Mar-2018) only applies to Win 10 Version 1709 (a.k.a the Fall Creators Update). The previous KB4074588 (OS Build 16299.248; released 13-Feb-2018) had a major bug that disabled many USB devices and onboard devices like a keyboard, camera or mouse, and KB4090913 was released to replace the buggy KB4074588. Information for both these Win 10 Version 1709 updates can be found at:February 13, 2018—KB4074588 (OS Build 16299.248)March 5, 2018—KB4090913 (OS Build 16299.251)

In January 2018 Microsoft released important security updates to patch a vulnerability known as Meltdown - see the Symantec article Meltdown and Spectre: Chip Vulnerabilities Could Facilitate Memory Leaks for more information . Microsoft required third-party antivirus companies like Symantec to set a registry key [Key="HKEY_LOCAL_MACHINE" Subkey="SOFTWARE\Microsoft\Windows\CurrentVersion\QualityCompat" Value="cadca5fe-87d3-4b96-b7fb-a231484277cc" Type="REG_DWORD” Data="0x00000000”] to ensure their antivirus product was compatible with the January 2018 patch for the Meltdown vulnerability and prevent possible BSODs - see the MS support article Important: Windows Security Updates Released January 3, 2018, and Antivirus Software. If that registry key is missing, Windows Update will stop delivering all security updates to prevent possible BSODs, and Windows Updates will resume once the registry key is created. That is why KB support articles for security updates released since January 2018 have noted that this registry key must be in the Windows registry - if that key is missing then Windows Update will not deliver the update.

If Windows Update is working normally on your machine and delivered the latest KB4090913 (OS Build 16299.251) for your Win 10 Version 1709 you can be relatively certain that the required registry key exists in your Windows registry. As PhoneMan noted <here>, if the registry key is missing and Windows Update has stopped working then a few manual LiveUpdates with Norton (Security | LiveUpdate) should re-create the registry key and get Windows Update working again.

As of March 13, 2018 Microsoft is lifting the AV compatibility check for the March 2018 Windows security updates for supported Windows 10 devices via Windows Update. We continue to require that AV software is compatible and in cases where there are known issues of AV driver compatibility, we will block those devices from receiving Windows updates to avoid any issues. Microsoft will continue to enforce this requirement for older versions of Windows until there is high confidence that the majority of customers will not encounter device crashes after installing the Windows security updates.
